Dry heat sterilization

Dry heat sterilization is a method used to eliminate all microorganisms, including bacteria and spores, by exposing objects to high temperatures without moisture. Typically, items are placed in an oven-like device called a dry heat sterilizer, where temperatures range from 160°C to 180°C (320°F to 356°F) for a specified period. This process destroys microbes through oxidation and protein denaturation, making it effective for heat-resistant materials like metal surgical instruments, glassware, and powders. It’s a reliable sterilization method that doesn't involve moisture or chemicals, reducing potential damage to certain items.
